Figure 2

Positive rate of wound bacterial culture (n = 55, %). The horizontal axis indicates the time points of bacterial culture, and the vertical axis indicates the positive rate (%). Before treatment and 1 week, 2 weeks, and 3 weeks after treatment, the numbers of positive cases in the control group were 28, 19, 12, and 2, respectively. Before treatment and 1 week, 2 weeks, and 3 weeks after treatment, the numbers of positive cases in the experimental group were 27, 9, 4, and 0, respectively. 1 week after treatment, the difference in positive rate between the two groups was significant (X² = 4.791, ). 2 weeks after treatment, the difference in positive rate between the two groups was significant (X² = 4.681, ).
